Trying this immediately.

Lily Collins's Instagram feed has always been one of our favorite sources of beauty inspiration, but her makeup and hair highlights reached new heights when she landed in the south of France for the Cannes Film Festival. After watching in awe as she debuted a never-ending parade of mesmerizing looks, we knew we had to go to the glam team behind her transformations. So, we hopped on the phone with celeb makeup artist Vincent Oquendo to get the details behind every single one of them.

"Lily has always reminded me of a modern-day Audrey Hepburn," he explained. "Especially with those brows! So naturally, we channeled that in Cannes. I thought about how Audrey would transform for her different roles when working with Lily. I had some time to think about all the beauty looks I was going to do — Mariel Haenn, Rob Zangardi, and Carrie Gordon at 42 West were such an amazing team to work with."

For Lily's first Cannes appearance, Vincent took his cues from Funny Face. "She starts off in the library and is scouted and goes to France," he says of the storyline that guided the makeup. "It's a classic look with a pop of pink on her lips." To get the face-freshening color, swipe on a coat or two of Lancôme Rouge in Love in Midnight Rose.

"Look two was her premiere look so I wanted it to echo Audrey transforming at the end of Funny Face," says Vincent. "The eye makeup was a direct reference from the movie." He paired Lily's lashes with a super-precise cat flick; for a similar effect, grab Lancôme Artliner in Noir. As for that otherworldly glow that made her skin literally look like porcelain? "I massaged her face for the red carpet," reveals Vincent. "When you have lymphatic drainage, it increases circulation and stimulates the skin."

Time for a metallic twist! "The silver eye was a reference from *How to Steal a Million," shares Vincent. "I loved the silver with the soft pinks." To coax a megawatt effect out of the pigment (recreate the look with Lancôme Color Design in Style Section), use this smart trick we learned from Vincent. "Wet your eyeshadow," he says. "I wet a fluffy brush and it makes those powders super pigmented. I took the same silver eyeshadow and applied it on the lid, then went over it with the wet brush. I also lay down some concealer on the lid so it has a base to hold to."

Lily totally caught us by surprise when she debuted a a head of gorgeous curls (created by Jen Atkin) on the carpet. Her makeup was every bit as stunning, too. "I was channeling the spirit of Audrey from Roman Holiday," explains Vincent. Rather than directly reference that makeup, he chose colors and textures that would evoke a fun, carefree attitude. "A white eyeliner paired with silver glitter was perfect," he says. (A non-patchy white liner can be tough to find, but we love Lancôme Le Stylo Waterproof in Rose Blanche.)

While there were plenty more Audrey Hepburn references to explore, Vincent chose to go a slightly different route for one of Lily's looks. "It's emerald-green eyeliner," he says (Lancôme Grandiôse Liner in Vert makes for the perfect, head-turning hue). "It felt tough and punky." To keep her base poreless, he used a combo of face masks and makeup. "Skincare treatments go such a long way," he says. "The better the canvas, the better the makeup. I always recommend a glowy foundation and a lightweight concealer." It's the secret to Cannes-worthy glam.
